Catalytic Converter for Ford Ranger (2007-2011) 4.0L Left & Right

Direct-Fit Stainless Catalytic Converter Set for 2007-2011 Ford Ranger (PN105)

What it Does: The catalytic converter assembly replaces degraded factory emissions units on the 2007-2011 Ford Ranger to restore exhaust flow velocity, clear OBD-II catalyst efficiency fault codes, and ensure reliable emissions compliance.

The Stock Ford Ranger Catalyst Degradation

Aging factory catalytic converters on high-mileage PN105 platforms frequently suffer from washcoat depletion, thermal fracturing, and internal honeycomb melt-down. Driven by prolonged unburnt hydrocarbons and thermal cycling from the Cologne 4.0L SOHC V6, the stock ceramic brick degrades, causing internal blockages that spike exhaust backpressure, sap engine efficiency, and trigger recurrent P0420/P0430 diagnostic trouble codes.

The Engineering Solution

Engineered as a bolt-on manifold-back solution, this dual-bank left and right catalytic converter set features a heavy-gauge Stainless Steel shell built to endure severe road spray, salt exposure, and thermal shock. Inside, high-flow ceramic washcoat substrates optimize catalyst light-off times while reducing exhaust restriction relative to clogged factory units. Precision-formed direct-mount flanges and accurate O2 sensor bungs eliminate the need for custom fabrication, slip joints, or pipe cutting during installation.
